ImagePlacementAbsorber

Inheritance: java.lang.Object

public final class ImagePlacementAbsorber

Represents an absorber object of image placement objects. Performs search of image usages and provides access to search results via ImagePlacementAbsorber.ImagePlacements collection.

The example demonstrates how to find images on the first PDF document page and get the image placement properties.


 // Open document
 Document doc = new Document("D:\\Tests\\input.pdf");
 // Create ImagePlacementAbsorber object to perform image placement search
 ImagePlacementAbsorber abs = new ImagePlacementAbsorber();
 // Accept the absorber for first page
 doc.getPages().get_Item(1).accept(abs);
 // Display image placement properties for all placements
 for (ImagePlacement imagePlacement : ```
(Iterable)
```abs.getImagePlacements())
 {
     System.out.println("image width:" + imagePlacement.getRectangle().getWidth());
     System.out.println("image height:" + imagePlacement.getRectangle().getHeight());
     System.out.println("image LLX:" + imagePlacement.getRectangle(0).getX());
     System.out.println("image LLY:" + imagePlacement.getRectangle.getY());
     System.out.println("image horizontal resolution:" + imagePlacement.getResolution().getX());
     System.out.println("image vertical resolution:" + imagePlacement.getResolution().getY());
 }

The ImagePlacementAbsorber object is basically used in images search scenario. When the search is completed the occurrences are represented with ImagePlacement objects that the ImagePlacementAbsorber.ImagePlacements collection contains. The ImagePlacement object provides access to the image placement properties: dimensions, resolution etc.

Image positive rotation is counterclockwise, for the page, it is clockwise. Here, we need to represent the image rotation angle, so we deduct the page angle from the image angle.
